Video Transcript for Roadmaster Tow Bar Wiring RM-146 Review

Today we're going to be reviewing part number RM-146. This is the RoadMaster's 6-Wire Flexo-Coil Kit. It's going to allow you to easily and effectively connect your motor home to your towed vehicle with the water, oil, and chemical-resistant electrical cord. The flexo-coil technology is going to allow the cord to extend more than 8 feet. Then it's also going to allow it to contract conveniently for storage and to resist dragging and tangling. The 6-Pole extension cord can be used for multiple towing applications. More than likely, it's going to be used for running power from your RV to your towed vehicle. It's going to come with 2 sockets.

One is going to mount to your RV and then one is going to mount to the towed vehicle for quick, easy hookup. The socket mounting brackets are going to be sold separately. You can find those right here at etrailer.com. You can see here how the sockets have the connectors here on the back for the wires to connect to. It runs through the rubber grommet or the rubber sleeve. Then, once it's mounted, all you've got to do is flip up the lid and then you can connect your extension cord directly to the connection points. It's got a nice spring-loaded lid, so it's always going to remain closed when that connected.

That way it's going to prevent any dirt or moisture from affecting the connection points. The flexo-coil cord, again, can expand more than 8 feet in length, yet still contract to prevent dragging and tangling. It's also going to provide convenient storage. We have silicone-injected plugs that are going to prevent corrosion. The electrical cord is resistant to water, oil, and chemicals. The plugs here on the cord have nice finger tabs on them. You can get a nice, secure grip on that. It makes for easy disconnect. The flexo-coil cords are not intended for use with RoadMaster all-terrain tow bars or any other tow bar that includes cable channel guides.

Only straight cords should be used with those models. That's going to do it for our review of part number RM-146. This is the RoadMaster 6-Wire to 6-Wire Flexo-Coil Kit. .

Was surprised to receive the product so quickly--about 4 days. The wire was top quality, but much cheaper than I could buy from any RV dealer which I contacted; shipping was more economical than I had expected. This was my second order from you, and I was pleased with both, 156020

Very well made, complete kit with a good quality socket for each end. I found the cable a bit short, although the coiled section allows the wire to stretch, the coiling is very strong and resulted in the plugs being pulled out of the sockets unless I strapped the sprung loaded lid to the plug. 8185

  • Flat Towing Wiring Extension 6-Pin To 6-Pin
  • The RoadMaster 6-Wire Flexo-Coil we offer comes in a kit as part # RM-146. This extension comes with the vehicle-end connector to mount to the RV and towed vehicle. I have attached an installation video of these connectors being installed on a 2014 Honda CR-V. If you do not need the vehicle-end 6-pin connectors, you could use the Hopkins Heavy-Duty Trailer Coiled Extension # HM47055. I have attached a review video of this extension for you.

  • Base Plate and Tow Bar Wiring Kit Recommendation for 2018 Jeep Wrangler JL Unlimited
  • For your 2018 Jeep Wrangler JL what you'd need is the Roadmaster Base Plate kit part # RM-521450-4 which is confirmed as a fit for your vehicle and will work well with your Roadmaster Stowmaster # RM-501. Then for wiring you'd need the part # RM-146 as a 6-way to 6-way coiled adapter and then for the wiring and diodes part # RM-152 and you'd be set.

  • How To Connect 4-Way Flat Vehicle Connector To 7-Way on Trailer
  • To connect your vehicle that has a 4-Way flat connector to your trailer that has a 7-Way connector, you will need to install a 7-Way on the rear of your vehicle. If you just want or need the tail light functions to operate on your trailer you will just need Adapter 4 Pole to 7 Pole, part # 37185. If you need the complete 7-Way wiring to operate, you will need Brake Controller 7 & 4 Way Installation Kit, part # ETBC7. The 4-Way on part # ETBC7 will plug into the 4-Way on your vehicle...

  • Kit and Instructions for Wiring Up Trailer to Convert 4-Way to 7-Way
  • We have a kit that's designed specifically for upgrading a trailer's 4-way to a 7-way. For that you'd want the upgrade kit part # ET7WK (if you don't have something like this already.) I attached a chart that details how this normally wires to a trailer for you to check out as well. In your situation the two wires with brown (and another color) are for the running light circuit but the rest SHOULD match color for color.

  • Is there a Plug-In Connector for Reverse Light Wire on ETBC7 Kit for a 2011 Toyota RAV4
  • To attach the reverse light wire from # ETBC7 to your 2011 Toyota RAV4 you will need to hardwire it directly to a reverse light circuit. There isn't a plug for it. The trouble is where to find the reverse light wire. You can test the wires at the tail lights to see if the reverse light wire passes through by using a circuit tester such as # ALL640595. If the reverse light wire cannot be found in the vehicle tail light wiring harnesses then you would need to get the signal from behind...

  • Adding a 4- to 7-Way Adapter with Reverse Circuit for Boat Trailer with Electric Reverse Lockout
  • Your trailer has an electric reverse lockout solenoid. When energized it will prevent the brake fluid from flowing back to the brakes so that you can back up. All you need is to install a 4- to 7-Way adapter such as # 37185 (if you need to replace the one you have). On the adapter there is a purple wire that you will need to tap into a reverse light circuit on your 2004 Honda Pilot. On the one you have the wire color may be different but as long as it is the one at the center pole then...

  • Installing Battery Charge Line Kit for Flat Towed Jeep Wrangler that has 4-Way Connector
  • I do have a solution for you, however you will not be able to use a pin on your existing 4-Way for a battery charge line.In order to run charge line from the RV to your 2008 Jeep Wrangler battery, I first recommend installing the Roadmaster 6-Wire Flexo-Coil Kit # RM-146. You will use this to connect the 6-Way on your RV to your Jeep. Simply cut off the 4-Way connector on the Jeep and hardwire in the included 6-Way, making sure to match the wires up by function. You can test the 6-Way on...

  • Which Pins of 6-Way are for 12 Volt Power and Ground
  • I attached a picture that has a diagram of how a 6-way wiring harness is pinned out. The center pin is the 12 volt power circuit and the pin in the 1:00 position on the female socket as you face the open connector is the ground circuit.

  • Recommended 7-Way Connector and Trailer Brake Controller for 2008 Acura MDX
  • Since your 2008 Acura MDX is already equipped with a 4-Way connector, you will just need the Universal Wiring Kit # ETBC7 to convert it to a fully functional 7-Way. This kit includes everything necessary to do this along with the extra wiring and circuit breakers required for installing a trailer brake controller. I have attached the complete installation instructions that you can also take a look at. Then for the brake controller I highly recommend the Tekonsha Prodigy P2 # 90885....

  • How to Install a 6-Way Trailer Connector To Front of Flat Towed Vehicle
  • It appears you are connecting your tow vehicle wiring to a 6-way connection like the RoadMaster 6-Wire Flexo-Coil Kit # RM-146. Making these connections is not difficult and I've attached a video and photo as well as linked an article to assist with these connections. You won't use the blue brake controller output location, but I do recommend connecting the 12V power using the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 to maintain your battery while towing.

  • Brake Controller and Install Wiring Recommendation for a 2009 Ford Escape
  • You will need to start with a 4-way (if you do not have one). For that you would want the # 118551. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling...

  • Trailer Wiring and Brake Controller Recommendation for 2007 Nissan Murano
  • You will need to start with a 4-way (if you do not have one) installed on your 2007 Nissan Murano. For that you would want the # 118775 which is a confirmed fit and would work well. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install...

  • Do Wire Colors Match When Replacing 4-Way Round with 4-Way Flat on RM-146
  • The wire colors will match once you remove the round 4-way of the # RM-146 and wire it to a 4-way like the # 18252.

  • Wiring 4-Way to 7-Way Adapter Help
  • Since I am not sure exactly what adapter you have the best solution I can provide currently is to have you check out the 7-way diagram I attached and wire up the wires of your 4-way to hopefully the same pin out. Otherwise the easiest to use adapter for your application is the part # 37185 which allows your 4-way to plug into it and converts it to a 7-way.
